Color-Keyed 54913BE – Frequently Asked Questions

1) Will the Color Keyed 54913BE lug take 250 kcmil copper cable?
That is exactly what it is sized for. The 54913BE is a one-hole, long-barrel compression lug rated for 250 kcmil cable, with a copper barrel. It is a single-size connector, not a range-taking mechanical lug, so a 4/0 or a 350 kcmil conductor needs a different die-coded lug.
2) Can I use this copper lug on a 15 kV or 25 kV medium-voltage termination?
Yes. The 250 kcmil Color Keyed long-barrel lug carries a 35 kV rating, which covers the common 5, 15, 25 and 35 kV medium-voltage classes. That is what makes it usable in substation and switchgear terminations rather than just 600 V panel work.
3) Can this lug be used to terminate aluminum conductor?
No. It is a copper-bodied lug for copper cable. Terminating aluminum conductor requires an aluminum or dual-rated AL9CU connector with the appropriate inhibitor compound. Using a copper-only lug on aluminum invites galvanic corrosion at the crimp.
4) Why is the lug yellow, and does the color mean anything for sizing?
Yellow is the color-key marking that identifies the conductor size and matching compression die for this connector. It is not a phase color and it is not insulation. The barrel is bare copper with no insulating sleeve, so once crimped you tape, boot, or shrink the termination yourself if the application calls for covering.
5) Is this lug UL listed for inspection sign-off?
It is listed under UL file E9809. For an AHJ that is the reference to cite along with the catalog number 54913BE. Note that a UL listing on a compression connector only holds if it is crimped with the die and tool the color key calls for.
6) What is the difference between a long-barrel compression lug and a standard-barrel one?
Long barrel gives more crimp length, which means two or more crimps per lug and a larger contact area with the conductor. Electricians specify it on high-current feeders and medium-voltage work where pull-out strength and low connection resistance matter. A short-barrel lug takes one crimp and is fine for lighter branch terminations, but it is not an equal substitute where the drawing calls out a long-barrel connector.
7) Do I need anything besides the lug to finish a 250 kcmil termination?
Plan on three things the lug does not include: a hydraulic or battery crimper with the die that matches the yellow color key, the 1/2 inch bolt, nut, and belleville or flat washers for the landing pad, and your own insulating buildup, since the barrel ships bare with no sleeve.
8) Is Color Keyed the same thing as Blackburn when I am matching what is already installed?
Same line. The connector is labeled Color Keyed / Blackburn, with Color Keyed as the sub-brand, so a 54913BE pulled off an existing Blackburn-stamped termination is the same catalog item you would reorder here. Country of origin is Mexico.
